are you blocking all traffic at the router? can you ping servers outside your network?
also, why o why are you running vmware and installing solaris with domino on top of that? domino is a f'in hog and probably one of the worst applications i've ever ran into. just thinking about running "server" gives me the chills. anyway, what does format say about how much you have allocated per drive/slice etc.
you want some real fun, install domino on a non-global domain and watch it try to write to /dev. its fun!
